Plumtree Software Examines Portal Architecture and Development Approaches at JavaOne Conference in San Francisco

Plumtree Software (Nasdaq:PLUM) today announced that
David Meyer, vice president of product management, will discuss Java
portal best practices and market approaches on a panel at the JavaOne
Conference in San Francisco on Tuesday, June 28, 2005. The panel,
entitled "Java(TM) Technology Portals Panel -- Leading Vendors Debate
Architecture and Development Approaches," will be moderated by
InfoWorld's Eric Knorr and includes speakers from BEA Systems, Sun
Microsystems and Vignette.
   Java is the dominant development platform for modern application
building, yet market-leading Java portals vary widely when it comes to
architecture. Plumtree's open portal technology affords companies the
unique ability to design applications on different platforms,
eliminating the constraints of a particular system built on a singe
stack. Additionally, Plumtree's portal platform provides enterprises
with the framework to create composite applications which can be
integrated into a cohesive Web environment.
   "With portal technology at the forefront of many service-oriented
architecture (SOA) strategies, it is no surprise that large enterprise
CIOs have ranked portal projects among their highest spending
priorities for 2005," said Meyer. "To that point, it is critical for
developers to fully understand the evolving standards and differing
architectural approaches of Java portal vendors to help determine what
will work best for their respective organizations."
